FREDRIOK BORNTRAGER, OF ST. CLAIR, MICHIGAN.

ROAD-CART.

SPECIFICATION forming part of Letters Patent No. 439,858, dated'November4,1890.

Application filed April 1, 1890. fierial No. 3461235. (No model.)

To all whom it may concern.-

Be it known that I, FREDRIOK BORNTRA- GER, a citizen of the UnitedStates, residing at St. Clair, in the county of St. Clair and State ofMichigan, have invented certain new and useful Improvements inRoad-Carts, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to new and useful improvements in two-wheeledvehicles; and the invention consists in the peculiar construction of thedevices for supporting the seat and foot rest and of adjusting the seatvertically, and, further, in the peculiar construction and arrangementof the various parts, as more fully hereinafter described.

In the drawings, Figure 1 is a vertical central section through myimproved cart. Fig. 2 is a rear elevation thereof. Fig. 3 is an enlargedside elevation of the heel of the shaft and heel-iron from which thespring is suspended.

A are the thills.

B is the axle.

G are the cross-bars of a road-cart of known and usual construction.

a b are the heel or thill irons for connecting the thill to the axle bymeans of the clip 0, the brace 01 forming a forward extension of theclip 0. The forward heel-iron a is of the usual construction; but therear heel-iron 17, instead of following the heel of the shaft in theusual manner, has the vertical portion 6 and the inclined port-ion f,the upper end of which is secured to the thill by means of the bolt 9.The heel-iron b is provided with the series of notches h.

D is the spring of semi-elliptic shape, having the usual eyes at itsends, to which are pivotally secured the clevises E and in which engagethe links F, which are engaged over the heel-irons b, and by placingthese links in the notches in the heel-iron b the spring is suspendedslightly in the rear of the axle and free to have a vertical or lateralmotion.

G is a seat, to which are secured the seatbars I-I, connected togetherby the slats I. The seat is supported upon the spring D by means of theseat-supporting frame J, secured to the seat-bars at its ends andcentrally connected upon the spring. The forward ends of the seat-barsare connected to the lower end of a C-spring K, which is secured at itsupper end to the cross-barC and embraces it, as plainly shown in 'thedrawings. It will thus be seen that the seat and seat-bars are supporteddirectly upon the semi-elliptic spring D, and at the forward ends theseatbars are also supported upon the Csprings, so that any vibration ofthe thills will not be transmitted to the driver, but will be taken upby the action of the C-springs.

Itis evident that the height of the seat may be adjusted to differentloads and to diflerent horses by engaging the links F in higher or lowernotches h in the heel-iron. The clevis and the link are twisted so thatthey will not bind in the use of the vehicle.

What I claim as my invention is-- In a road-cart, the combination, withthe axle and shafts, of the heel-irons a 12, secured to the shafts andextending below the axle in the front and rear, respectively, of theshaft, the brace d, the clip 0 integral therewith, forming a connectionbetween the heel-irons and constituting an extension of the brace, thevertical extension e of the rear heel-iron having notches h in its edge,the inclined brace portion f, integral therewith and projectingobliquely forward and forming an extension of the extension e, havingits forward end secured to the shaft, and a seat-supporting springadjustably secured to the extensions e, substantially as described.

In testimony whereof I affix my signature, in presence of two witnesses,this 21st day of March, 1890.

FREDRIOK BORNTRAGER.
